Abstract

A method (600) of one embodiment of the invention is disclosed that is for a track of an optically writable label region of an optical disc having a non-integer number of pixel positions around the track, such that a last fractional pixel position is defined. The method determines whether the size of the last fractional pixel position is greater than a fractional threshold (604). In response to determining that the size of the last fractional pixel position is greater than the fractional threshold (606), the method writes a complete pixel to the last fractional pixel position, such that the complete pixel written overlaps onto a first complete pixel position of the track (608).
